I came across this event listing on our Calendar page and had to share:

Location: Marriott Renaissance Hotel
Contact: Marjory Mogg - marjorymogg@bouchercon2012.com
Event Details: The oldest and largest annual mystery books conference will bring $1 million to $2 million to Cleveland in October. The Bouchercon World Mystery Convention has been held annually in various cities since 1970, but has never been hosted in the state of Ohio. Downtown restaurants and clubs can expect to entertain over 1,500 mystery fans, authors, and publishers with plenty of time to explore the city. The conference will be held at the Marriott Renaissance Hotel on October 4 – 7, 2012.
The Bouchercon itself, and the Anthony Awards, which are announced at the conference, are named in honor of the renowned author, editor and mystery devotee, Anthony Boucher (rhymes with voucher). The theme of the 2012 conference will be “Crime Fiction Rocks,” with the opening ceremonies to be held at the Rock & Roll Hall of Fame and Museum.
Guests of honor for 2012 include authors Elizabeth George, Robin Cook, John Connolly, and Cleveland’s own Les Roberts. Mary Higgins Clark will be recognized with an award for lifetime achievement.

The chair of the conference is Cleveland area librarian, Marjory Mogg.
